The 2006 Yamaha YZF-R1 LE livery, which was a yellow, black, and white homage to Kenny Roberts Sr., is perhaps the greatest livery ever to adorn an R1, straight from the Yamaha factory. Whether you are a loyal subject of King Kenny, or you just enjoy the fetching, yet simple, racing design, the Roberts livery is a treasure to see in any form — but especially so at speed. Giving us a glimpse as to what the 2015 Yamaha YZF-R1 would look like with such a limited edition paint scheme, Oberdan Bezzi has once again whet our appetite ahead of a weekend full of riding. And for you Giacomo Agostini fans, there is something special waiting for you after the jump as well. Enjoy!

After first showing us the Honda SFA and Honda CRF250 Rally concepts, Big Red made good on its promise for another motorcycle concept premiere at the Osaka Motorcycle Show, debuting the Honda Bulldog concept. With the face of a Ruckus, and built to “leisurely” take-on the great outdoors in an unassuming manor, the Honda Bulldog is a stout off-roader that adds a new slant to the term adventure-bike. With wide 15″ knobby tires, a 28″ seat height, and 400cc parallel-twin engine mated to a six-speed gearbox, the Bulldog certainly isn’t what you expect to see bombing down the trails, yet it sorta makes sense.

If you believe the reports coming out of India and Southeast Asia, Yamaha is working on a naked version of its YZF-R25 sport bike. Presumably to be call the Yamaha MT-25, the naked bike would continue Yamaha’s trend of making naked version of its fully faired sport bikes, similar to the recently released Yamaha MT-125 that is available for the European market. With images of the machine testing on public roads abounding, the MT-25 seems likely to see production, so the real intrigue will be in what markets Yamaha makes the machine available. With Honda already offering faired (Honda CBR300R) and unfaired versions (Honda CB300F) of its small-displacement motorcycle in the US, Yamaha could easily go head-to-head with Big Red with the YZF-R3 and an FZ-03 variant, based off the R3 design.

Need further proof that the future of motorcycling will include electrics? Take this recently published patent application from Kawasaki, that the Japanese OEM filed for back in 2011. The claims are fairly rudimentary, though they do include a transmission, with Kawasaki’s lawyers mostly outlining the basics of a motorcycle powered by an electric motor, of course the news is less about the contents of the patent application, and more about the fact that it was applied for, in the first place. When will we see an electric motorcycle concept from Kawasaki is anyone’s guess, though there are two big motorcycle shows coming up in Japan in a couple weeks’ time. In reality, we doubt we’ll see something so soon from Kawasaki, but if the Kawasaki H2 has shown us anything, it is that anything is possible from Kawasaki right now.

Why would KTM be riding around on a camouflaged Aprilia Tuono V4? That is the question of the day, after a spy photographer caught the Austrian company testing in Spain with such a machine. The answer of course points to KTM working on a V4 street bike platform, which shouldn’t be too surprising since KTM CEO Stefan Pierer already tipped the media off to the fact that it is working on a MotoGP entry that would be based around a beastly V4 engine called the RC16. While Pierer confirmed the MotoGP, as well as a track-only consumer version of the GP bike, zie Austrians have been mum about other motorcycles in KTM’s lineup sharing the new V4 powerplant.

Adventure riders, you prayers have been answered. Honda is set to debut a new off-road model at the Osaka Motorcycle Show, the Honda CRF250 Rally. Based off the Honda CRF250L platform, the Rally concept is basically the CRF250L with rally-styled bodywork. The Honda CRF250 Rally concept will get its worldwide debut alongside the Honda True Adventure concept, which we first saw at last year’s EICMA show. This makes for an interesting dichotomy, as the CRF250 Rally is set to look like the CRF450 Rally race bike, while the True Adventure (cough, Africa Twin, cough) borrows heavily from the race bike’s technology package. With Honda showing a 250cc ADV model and a 1,000cc model at the same show, one has to wonder when a consumer-level version of the CRF450 Rally race bike will be ready as well.

After it first debuted in Indonesia last October, the Honda SFA concept motorcycle seems to be getting serious, as Honda will be showing the up-market bike at this weekend’s Osaka Motorcycle Show and next weekend’s Tokyo Motorcycle Show. While Honda only mentions that the SFA concept is a “street-fighter style light-weight motorcycle with a single cylinder engine mounted on a trellis frame,” sources in Indonesia say the fetching small-displacement machine is built around the 150cc CB150R for that market. Whether this means that Honda will make more premium-focused 150cc machines, and bring them to markets outside of Asia remains to be seen, though it is clear that the Japanese firm is taking such an approach under serious consideration.

Italy’s favorite boutique brand will be back at the Isle of Man TT races this year, with a two rider team that includes American Brandon Cretu. Cretu and his teammate Ben Wylie will campaign for Bimota at the big four road races (North West 200, Isle of Man TT, Ulster Grand Prix, and Macau GP) on-board the Bimota BB3 superbike. This is not the first time that Cretu and Wylie have raced together, having shared a pit while at the Wylie Racing team during the 2011 and 2012 Isle of Man TT races. Though the Bimota BB3 was ruled ineligible for FIM events, the international road racing scene has no hang-ups letting the S1000RR-powered superbikes lineup on the starting grid.

We are still waiting for the 2015 MV Agusta F4 RC to break cover officially, but the top-of-the-line superbike from Varese continues to make itself sneakily available to the public. First there were the leaked studio photos, which looked spot-on to the photos MV Agusta USA teased us with at its press launch earlier this year. Now, we have more photos of the F4 RC leaking, though with some changes to the design — namely more prominent “AMG” badging, for MV Agusta’s newest minority partner. The 2015 MV Agusta F4 RC isn’t supposed to arrive at dealerships until June 2015; and when it does, it will be in limited numbers. The F4 RC is MV Agusta’s homologation special for World Superbike and domestic superbike racing classes.

Aprilia Racing boss Romano Albesiano has big shoes to fill. Taking over from Gigi Dall’Igna, Albesiano must continue the legacy of success which his predecessor left for him. He got off to a good start, Sylvain Guintoli lifting the World Superbike title in Albesiano’s first year at the helm. Now comes the hard part, following up on that success and expanding into MotoGP. A small group of journalists spoke to Albesiano at the Aprilia launch in Milan. In a wide-ranging conversation, the Aprilia boss covered many topics, including explaining why the Noale firm came back to MotoGP a year ahead of schedule, touching on what the new bike Aprilia is working on for 2016 and beyond might look like, and the 2016 rules in MotoGP.

The guys and gals over at Autoblog never cease to disappoint when it comes to finding some of the most outrageous automotive concoctions on the internet, and today is no exception.

Someone had the audacity/genius, to completely rip out the guts of a 2008 Toyota Prius, and stuff in a Harley Davidson motor from 1986.

While some will be cringing in terror and anger after seeing the Captain Planet mobile so horribly butchered, remember that the “Toyohog”, as the team calls it, was built to compete in the 24 Hours of LeMons, and maybe win the “Albert Gore Jr. Carbon Neutral Cup”, one of the many LeMons season prizes.

Oregon’s favorite motorcycle apparel brand has a custom motorcycle build for the holidays, the Icon 1000 “Iron Lung” Sportster. An homage to the bikes that Harley-Davidson used to build in the 1970’s, you know when the Bar & Shield brand did real racing, and was fairly good at it too.

Based around a 1991 Harley-Davidson Sportster 883 engine, the Iron Lung sees its lump bored out to 1,200cc, with a Supertrapp exhaust helping things breathe a bit better as well. The front-end has been lowered and widened with wide-glide forks and custom triple clamp. Similarly, the rear features a custom subframe with Progressive 970 shocks.

To make Iron Lung work visually, Icon widened the fairings, which gives the machine a bulldog like stance: low and wide. Fitted with the company’s own variety of Portlandian hipster chic, the Iron Lung sports paint by Garage 31 and a custom seat by New Church Moto — two local outfits in Portland, Oregon.

The design isn’t really our usual fare here at Asphalt & Rubber, but you have to appreciate the honesty in Icon’s retelling of the Iron Lung’s performance assessment:

“Once completed, we headed down to an oval in Southern Oregon and kicked ‘er in the guts to be featured along side of our Spring 2014 ICON 1000 apparel collection – coming soon. Her handling was as questionable as the grandstand snacks, but she bore the brunt of torture with aplomb. It wouldn’t be an ICON 1000 bike without a true trial by fire. In Iron Lung’s case this was literal as she burst into flame after her initial shakedown run just a few weeks prior.”

We’ve gotten more than a few emails from readers between the ages of 18-30 saying they’ve been approached at motorcycling events by market research company representatives working for Harley-Davidson. In conjunction with beefing up its Sportster line-up (the goto motorcycle at Harley-Davidson for catering to Gen-Y/X riders) with more youth-oriented motorcycles, Harley-Davidson is clearly trying to latch onto a new generation of rider.

Looking for the next generation of rebels, Harley’s focus lately has been on the skateboarding inclined, hoping perhaps that the demographic’s lifestyle of “skateboarding is not a crime” is a value that transfers over easily to two-wheeled transportation. Of course this marketing effort wouldn’t be complete without a new ad campaign, and Harley is clearly making ads for the customer it wants, not the customer it has.

Giving credit where credit is due, this is one of the better ads to come out of the Milwaukee brand. Check the video out after the jump, and note how many times you see a woman behind the handlebars.

The Harley-Davidson Sportster Forty-Eight (or is it 48?), has made its way out of Milwaukee in time for the 2010 model year. Based on the Sportster 1200 platform, the Forty-Eight is the latest addition to Harley’s “custom” offering. It differs from its Nightser et al counterparts with a bobber meets cafe racer appeal, but keeps the ubiquitous orange and black color schemes.
